temptation and peer pressure

Man college life is so different there is so much going on. I love to the opposite sex (females). and there are so many here and i think that a lot of them seem interested in me... (that makes me smile) lol. but there are three problems with that! one is that one of the girls that show interest has a boyfriend... and i am not the type to break up a happy home. and problem number two some of the other girls that show interest, i dont like them at all. and last but not least problem number three is the other one i slightly (not much at all) have interest in and we have our little time together.. but i dont wont to continue to lead her on and hurt her feeling if i am not ready to be in a relationship or be tied down. but the temptation of being with her is a lil strong..
